The light/s flash therefore the machine is responding to your command to power up, from this you can deduce that power is reaching the mobo as this controls the lights.

Thats why I suspect the mobo power control, and, in my experience no beeps with no memory = mobo buggered, unless another device connected to the mobo has gone short stopping the mobo powering up to protect it.

My next move would be to uncouple the cd, hd, and any other peripherals and try to boot, if the lappy beeps then you know you have a fault in one of the peripherals and can try plugging them back in one at a time and see when the mobo fails to boot/beep.

As above could also try a bios reset.

Hope this helps you.

There might be password protection in the bios by the sounds of it, go into the bios and see if it will let you switch it off (the password protection), if not you will have to reset the bios to get rid of any bios password protection, not forgetting that the time/date will want correcting in the bios (if reset) on first start up.

if u have done bios reset, and u didnt have poweron password enabled b4 then i think it will be just rtn and then enter bios to turn off poweron password. If u had poweron password b4 then u will need to put in what it was b4.

also memory in socket is upgrade memory so there is the base memory still in lappy when u remove sodimm
